The. thermal trip signal was initiated by flow com- parator problems. The flow compara- tor problems were due to vetting of recirculating flow transmitters in the north core spray room. Water entered the room through a sump pump discharge line open check valve from a radwas'te. tanic. Water was being discharged from the room through a temporary hookup . through the Service Water System due to high salt water content when the back- . flow occurred through the installed - sump pump line. The normal system could not be used because the Radwaste System is not designed for high con- ductivity salt water.

The long terrn corrective action will be to complete a submitted EWR (#79-37) for storar.e of high conductivity water that rad- waste cannot process. This will allow high conductivity water to be pumped - ~ to storage immediately and processed - or released after sampling. - . - I 2 3 4 - F: Forced Reason: Method: Exhibit G. instructions S: Scheduled A-Equipment Failure (Explain) 1-Manual for Preparation of Data .
